Definitions

  • the invention relates to a system for reconstituting beverages using superheated constituting liquid to simultaneously effect a sterilization or pasteurization of the beverages. More particularly, the invention relates to a system of the aforementioned type wherein the reconstituting process can be intermittently interrupted and restarted again without any risk of product degradation or loss of aseptic conditions.
  • processes have been developed wherein both steps are carried out simultaneously.
  • processes have been developed wherein water is heated to a temperature such that it produces a reconstituted product whose temperature is similar to that at which pasteurization is to be carried out.
  • Another problem which can occur during a shutdown is degradation of product in the mixing chamber caused by prolonged exposure of the concentrate to high temperatures.
  • a mixing chamber which can be adjusted so as to minimize its volume during a shutdown of the apparatus thereby allowing the chamber to be flushed with a small amount of water and permitting cooling and reheating of the chamber without the risk of altering the flavor or other qualities (e.g., Brix) of the product.
  • the invention provides a method and apparatus for reconstituting beverages wherein superheated constituting liquid and beverage concentrate are delivered into a mixing chamber.
  • the mixing chamber is located between two coaxially arranged tapered elements which are disposed one inside of the other.
  • Final beverage product emanates from an aperture in the tip of the outer tapered element.
  • At least one tapered element can be displaced in the longitudinal direction so that the volume of the mixing chamber approaches zero as the tapered elements are moved closer together.
  • the temperature of the mixing chamber can be controlled during a shutdown by adjusting the temperature of water contained within the walls of the tapered elements.
  • Figure 2 is a detailed cross-sectional view of the mixing tube used in the present invention in the mode where product is being made.
  • Figure 3 is a detailed cross-sectional view of the mixing tube used in the present invention in a shutdown mode.
  • Figure 4 is a top cross-sectional view of the mixing tube used in the present invention.
  • a tank 10 for holding the syrup or concentrate which is to be reconstituted Piping 11 connects tank 10 to the mixing chamber.
  • a metering pump 12 pumps the syrup toward the mixing chamber at a preset flow rate.
  • Metering pump 12 and the flow rate are controlled by a control regulator 13.
  • a valve 14 is disposed in piping 11 downstream from metering pump 12. In the making product mode, valve 14 is adjusted to direct the flow of syrup toward the mixing chamber 42. In the stop product mode, valve 14 is adjusted to redirect the syrup into return piping 15 back in the direction of tank 10 and piping 11 so that the flow of syrup into the mixing chamber is discontinued.
  • Water from a supply 16 is pumped through a filter 17 from a control valve 18 and then to a heat exchanger 19 where the temperature of the water is lowered for reasons which will later become apparent.
  • the chilled water is then passed to a chilled water tank 20 where it may be stored during a stop product mode.
  • water from tank 20 is pumped by means of pump 21 through piping 22 to a temperature control sensor 23. If the temperature of the water is not low enough (i.e., about 35°F), the water is recirculated back to heat exchanger 19 through piping 24. If the temperature of the water is sufficiently cool, it continues through piping 22 onto heat exchanger 25 where it is heated by heat from the final beverage product previously formed. At the same time, in heat exchanger 25, the final beverage product is cooled by the chilled water. In heat exchanger 25 the chilled water can be heated to a temperature of about 178°F.
  • the hot water is pumped through piping 26 from a control valve 27 which is coupled to control regulator 13 and which can be adjusted thereby.
  • the water then passes a temperature control sensor 28. If the temperature control sensor 28 senses that the temperature of the water is below a predetermined level, for example about 178°F, a valve 29 is automatically adjusted to redirect the flow of water through piping 49 back to a cooling tower 30 and then back to heat exchanger 19. On the other hand, if the temperature of the water is sufficiently hot, valve 29 directs the water to hot water tank 31.
  • Hot water tank 31 includes a booster heater 32 to allow the temperature of the water to be maintained or raised if necessary.
  • the reconstituting water is deaerated by a conventional deaeration means 33 associated with the hot water tank 31. Deaeration of the reconstituting water reduces the risk of undesirable oxidation of vitamin C and flavor components of the product during blending. In this way flavor changes are avoided.
  • the hot water tank 31 can also store reconstituting water during a stop product mode.
  • deaerated water from tank 31 is pumped through piping 34 by pump 35 to superheater 36 where the water is superheated under pressure to temperatures in excess of its boiling point.
  • the flow rate of water to the superheater can be adjusted by control means 37 linked to control regulator 13.
  • superheated water must be maintained under a pressure to prevent boiling.
  • the pressure can be on the order of about 18 x 10 5 Pa, The water must be heated to a temperature above the temperature at which heat treatment of the concentrate is to occur.
  • the reconstituting water could be superheated to about 135°C, the difference in temperature depending on the nature and the temperature of the syrup and its proportion in the final beverage product.
  • the superheated water is pumped toward the mixing chamber 42 at a preset flow rate through piping 38.
  • Piping 38 includes a valve 39 downstream from pump 35.
  • Valve 39 is also linked to control regulator 13.
  • valve 39 is adjusted to direct the flow of superheated water into the mixing chamber 42 through piping 40.
  • the valve 39 is adjusted to redirect the water back to piping 41 and back to hot water tank 31 through a path which will be described hereinafter.
  • the mixing tube includes a mixing chamber 42 which is the volume between two tapered members 43 and 44.
  • Members 43 and 44 can be hollow cylinders which are tapered at one of their respective ends as illustrated in Fig. 2.
  • the tapering of the cylindrical members is accomplished by making them conically shaped at one of their respective ends as illustrated in Fig. 2.
  • the tapered ends could be concave, convex or spherical. What is important is that the shape of the members 43 and 44 be such that the volume of the mixing chamber between the tapered sections of the members 43 and 44 decreases and approaches zero as the members are moved closer together.
  • members 43 and 44 are coaxially arranged.
  • Inner member 43 can be displaced in the longitudinal direction along its axis thereby changing the volume of the mixing chamber 42.
  • inner member 43 is pushed down so that its tapered section is moved in closer proximity to the tapered section of outer member 44 thereby decreasing the volume of the mixing chamber 42 which approaches zero.
  • the mixing chamber 42 whose volume is very small, can be closed by a back pressure valve 45 to prevent product from traveling downstream.
  • Inner member 43 is driven downward by a piston 46 which is mounted for movement within a cylinder 66 which is positioned on top of and concentric with outer member 44.
  • valve 14 In order to shutdown the system, valve 14 is adjusted to direct syrup away from the mixing chamber in the manner previously described. Likewise, valve 39 is adjusted to redirect the flow of superheated water away from mixing chamber 42. The drop off in volume of water and syrup in the mixing chamber allows piston 46 to drop down. In addition, the superheated water will be directed by valve 39 into piping 41 which feeds into the top of the outer member 44 to force piston 46 down, thereby reducing the volume of the mixing chamber (see Fig. 3). Valve 45 should also be closed at this time. In this way, product which has not been completely sterilized in the mixing chamber is prevented from proceeding downstream from the mixing chamber thereby ensuring the sterility of the remainder of the system during a shutdown.
  • Piston 46 is formed with channel 50 which feeds into a water jacket 51 around the surface of inner member 43. Water from piping 41 forces piston 46 down and then is forced through channel 50 and into water jacket 51. The water flows down jacket 51 of inner member 43. If inner member 43 is formed with stiffening rings 52 for support, the stiffening rings 52 must also be formed with channels 63 to allow for water flow. The water is then forced back up center channel 53 of inner member 43. The top of center channel 53 feeds into piping 54 which carries the water past a pressure relief valve 55 back into hot water tank 31. During prolonged shutdowns, the flow of superheated water can be stopped at the source rather than redirected into piping 41.
  • the temperature of the mixing chamber 42 can be lowered by turning off or bypassing the heating elements of the system so as to circulate chilled water through water jacket 51 of the tapered member 43 to prevent product degradation.
  • the temperature of product in the mixing chamber can be raised by activating the heating elements and circulating hot or superheated water through the water jacket 51.
  • the mixing chamber can be brought back to sterile conditions before valve 45 and the chamber are opened so that there is no danger of contaminated syrup coming in contact with the sterile downstream environment.
  • the temperature of the material in the mixing chamber 42 can be quickly lowered and raised during the stop product mode because of the small volume of material present in the mixing chamber 42.
  • the outer member 44 may optionally be surrounded with insulation 57 immediately adjacent to mixing chamber 42.
  • the invention provides a system for the aseptic reconstitution of beverages.
  • the invention has been described with reference to specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made thereunto without departing from the broader spirit and scope of the invention as set forth in the appended claims.
  • the specification and drawings are accordingly to be regarded in an illustrative rather that a restrictive sense.
  • the mixing holding tube of the invention can have a wide variety of applications other than aseptic reconstitution of beverages.
  • the mixing/holding tube can be used in the preparation of pharmaceuticals, alcoholic beverages and various food products.

Abstract

Procédé et appareil destinés à reconstituer des boissons, dans lesquels un liquide de reconstitution surchauffé et un concentré de boisson sont acheminés dans une chambre de mélange à volume réglable. Ladite chambre de mélange est le volume (42) situé entre deux éléments coniques disposés coaxialement (43, 44), l'un se trouvant à l'intérieur de l'autre. Le produit final s'écoule par un orifice (48) situé à l'extrémité de l'élément conique extérieur. Un élément conique au moins peut être déplacé dans la direction longitudinale de manière à ce que le volume de la chambre de mélange diminue et approche de zéro à mesure que les éléments coniques se rapprochent de plus en plus l'un de l'autre. Par conséquent, lorsque le système est hors service, le volume de la chambre de mélange approche de zéro, si bien qu'une très petite quantité de produit est susceptible de se dégrader dans la chambre de mélange en raison d'une exposition prolongée à des températures élevées pendant la mise hors service. La chambre de mélange de volume réduit peut être rincée à l'aide de liquide de reconstitution. De plus, la température de ladite chambre de mélange peut être commandée pendant une mise hors service en réglant la température de l'eau contenue à l'intérieur des parois des éléments coniques.
